Description

Technical Field

[0001] The invention relates to the field of electric power technology, and in particular to a ignition device and a control method thereof. Background Art

[0002] Live connection of the distribution network is one of the main operations in live operation, which requires connecting one end of the high-voltage drainage line to the high-voltage busbar.

[0003] High-voltage drain wire is a common power system equipment, and its main function is to shunt or guide extra current to prevent other components from being damaged by overload or arcing. Due to its good insulation and protection, the drain wire can also carry and isolate current to ensure the safe operation of other power equipment. In the voltage distribution devices of power plants and substations at all levels, the busbar is a conductor that connects large electrical equipment such as generators and transformers with various electrical devices to build a bridge. It has the functions of collecting, transmitting and distributing electrical energy. The bridge role played by the busbar is the basis for the normal operation of the power system.

[0004] In the live connection operation of the distribution network, one end of the drainage wire at the secondary support of the high-voltage power pole needs to be stripped and connected to the stripped busbar at a higher place, while the other end of the drainage wire, i.e. the root, remains fixed at the secondary support. After the drainage wire is connected to the busbar, the live wire clamp fixes the two together to achieve conduction between the drainage wire and the busbar.

[0005] The parallel groove wire clamp is one of the commonly used live wire clamps, which has the advantages of corrosion resistance, earthquake resistance, convenience, and high efficiency. Manual installation of the parallel groove wire clamp has a high risk factor, and the torque applied to the bolt varies from person to person, resulting in poor consistency in the pressure of the wire clamp on the wire. The pressure between the wire clamp and the wire is too large, and the creep of the wire is too large; the pressure between the wire clamp and the wire is too small, and the wire clamp and the wire are not pressed tightly enough. Using a live wire connection device to install the wire clamp has a high safety factor and better guarantees the installation quality. The replacement of manual operation with a live wire connection device is an inevitable development trend for high-voltage live wire connection operations.

[0006] When using the fire connection device to drag the drain wire, the drain wire will inevitably bend and twist. The wire clamping assembly of the existing fire connection device only has the function of clamping the drain wire. The drain wire is limited circumferentially by the inner wall of the wire trough it contacts and cannot be converted into effective twisting, which makes dragging more and more difficult, thus affecting the operation process, and it is also easy to damage the clamping claw and its base. In addition, as the number of twisting turns increases, the outer skin of the drain wire is worn, thereby affecting the safe use of the drain wire. Moreover, due to the friction of the outer skin against the inner wall of the wire trough, the metal conductor inside the drain wire may be displaced or fall off relative to the outer skin, thereby affecting the transmission performance of the drain wire.

Then, the fire connection device carrying the drainage line is moved to the busbar position to install the wire clamp. When the drainage line is moved and dragged, the drainage line is placed between the wire clamping sub-components on both sides when the drainage line is moved by the wire clamping assembly. The first driving mechanism is controlled to drive the wire clamping sub-components on both sides to clamp the drainage line in the wire clamping space, and the drainage line is axially limited based on friction. When the drainage line is twisted during the dragging process and a torsional force is applied to the roller, since the roller is set to a rotatable design, the torsional force of the drainage line on the roller can overcome the friction resistance of the roller and drive the roller in contact with it to roll, so that the drainage line can be twisted continuously, and the continuous twisting will not hinder the dragging of the drainage line, thereby improving the operability of the dragging operation.

[0084] In addition, the friction torque of the roller on the drainage wire skin is released, which effectively solves the problem of wear of the drainage wire skin. At the same time, the wire skin will not be twisted relative to the inner core, which can avoid misalignment or displacement of the inner core and ensure the transmission performance and safety characteristics of the drainage wire.

[0112] When the drainage wire is dragged using the wire clamping assembly of the present embodiment, the drainage wire twists and is subject to the frictional resistance of the roller 12. Since the roller 12 is rotatable, the torsional force exerted by the drainage wire on the roller 12 can overcome the frictional resistance of the roller 12, driving the roller 12 in contact with it to roll. In this way, the drainage wire can continue to twist, reducing the difficulty of dragging. In addition, the rolling friction of the roller 12 on the wire skin of the drainage wire is released, effectively solving the problem of frictional damage to the wire skin. At the same time, the wire skin will not twist relative to the inner core, which can avoid misalignment or displacement of the inner core, thereby ensuring the transmission performance and safety characteristics of the drainage wire.

[0113] Figure 5 An application scenario of the clamping assembly of this embodiment is given, that is, to perform a lead wire splicing operation, and to use the clamping assembly to drag and lift the lower drain wire 100 to the higher busbar 200 position for connection. One end of the drain wire 100 is connected to the secondary support of the high-voltage power pole, and the clamping assembly clamps the other end of the drain wire 100, i.e., the free end, to drag and lift the drain wire 100 from a suspended state to the connection position.

[0114] In the process of dragging and lifting the drainage line 100, the roller 12 (see Figure 4 ) assists the drainage wire 100 to steadily release the friction torque exerted on the wire skin.

[0115] In the embodiments of the present disclosure, Figure 4 As shown, each wire clamping sub-component 10 includes two rollers 12 arranged along the second direction BB′.

[0116] In this embodiment, the outer peripheral surface of the roller is formed with an annular protrusion 120 surrounding the first rotating shaft 13. In this way, when clamped, the annular protrusion 120 can cause the skin of the drainage line to deform, thereby slightly pressing into the skin of the drainage line, thereby enhancing the drainage line 100 (see Figure 5 ) to better prevent the drainage wire 100 from escaping from the wire clamping assembly during the transfer or wire feeding process.

[0117] In the embodiment of the present disclosure, a plurality of annular protrusions 120 are provided on the outer peripheral surface of the roller, for example, including an annular protrusion 120 located at both ends and between the two ends. The number, spacing or distribution density of the annular protrusions 120 can be set as required. In an optional manner, the fewer the number of annular protrusions 120 or the smaller the distribution density, the greater the drainage line 100 (see Figure 5 ) The smaller the contact area between the roller 12 and the annular protrusion 120, the more the annular protrusion 120 can press into the drainage wire skin, thereby enhancing the axial limit. The more the annular protrusions 120, the smaller the pressure of the annular protrusions 120 on the wire skin, the smaller the possibility of the annular protrusions 120 pressing into the wire skin, and the axial limit of the drainage wire 100 will be weakened.

[0118] In the embodiment of the present disclosure, the outer peripheral surface of the roller may also be formed with at least one group of protrusions distributed around the first rotating shaft 13, and each group of protrusions is independently distributed in an annular shape. This can also achieve the axial limiting effect of the annular protrusion in the above embodiment.

[0119] In this embodiment, the shape of the protrusion can be a round protrusion or a square protrusion or a protrusion of other shapes, wherein the round protrusion has a smooth surface and few sharp protrusions, which can play a good anti-damage effect. The shape of the protrusion is not limited here.

[0120] In addition, the distribution density of each group of protrusions along the circumference of the first rotating shaft 13 can ensure that when the drain line 100 is clamped (see Figure 5 ), the contact area between the drainage line 100 and the roller 12 is reduced to enhance the axial limiting effect.

[0121] In an optional manner, each roller may also include a plurality of discrete ring members axially connected in series along the first rotating shaft, which can also achieve the effect of the above-mentioned annular protrusion.

[0122] This embodiment provides an implementation method for assembling the support portion 11 and the roller 12. The support portion 11 has a receiving groove 11a opened along the first direction AA' facing the other side clamping sub-component 10, the first rotating shaft 13 is located in the receiving groove 11a, the support portion 11 includes two side edges 111 arranged opposite to each other along the third direction CC' parallel to the first rotating shaft 13 and used to form the receiving groove 11a, the first rotating shaft 13 is fixedly connected to the two side edges 111, and the roller 12 is rotatably sleeved on the first rotating shaft 13 and partially extends out of the receiving groove 11a along the first direction AA'.

[0123] The electric drain wire, especially the large cross-section drain wire, is heavy and hard. During the dragging process, it is 100% (see Figure 5) The structural parts in contact with the drain wire 100 have to bear a large force from the drain wire 100. The receiving groove 11a is designed so that most of the roller 12 is hidden in the receiving groove 11a, so that the outer surface of the receiving groove 11a helps to bear the force from the drain wire 100, preventing the drain wire force from damaging the roller 12.

[0124] In the embodiment of the present disclosure, each support portion 11 is formed with an outer flange 112 along the first direction AA' relative to the other side of the clamping sub-component 10 at the top of the second direction BB'. The outer flange 112 of the clamping sub-components 10 on both sides forms a larger wire inlet 11b, which is conducive to the drainage wire 100 (see Figure 5 ) Enter the wire receiving clamping space between the wire clamping components 10 on both sides from the wire inlet 11b, and guide the drainage wire 100 to slide over the inner side of the outer flange 112 and enter the wire receiving clamping space.

[0125] In the embodiment of the present disclosure, the first driving mechanism 20 is used to drive the two side clamping sub-components 10 to separate and clamp. The first driving mechanism 20 specifically includes:

[0126] A first rotating motor 21 having a first motor output terminal 2b;

[0127] A first transmission mechanism 22 having a first rotation input end 2c and first translation output ends 2a at both ends arranged along the first direction AA', connected to the first motor output end 2b through the first rotation input end 2c to input rotational motion, and connected to the support parts 11 of the clamping sub-components 10 at both sides through the first translation output ends 2a at both ends;

[0128] The first transmission mechanism 22 is configured to convert the rotational motion into the movement of the first translational output ends 2a at both ends toward or away from each other along the first direction AA′.

[0129] In this embodiment, the first transmission mechanism 22 is used to convert the rotational motion into the reverse linear motion of the first translational output ends 2a at both ends, which includes the movement toward and away from each other. By controlling the first rotary motor 21 to switch the rotation direction, the rotation direction of the first rotary input end 2c is changed, and the movement toward and away from each other of the first translational output ends 2a at both ends is switched, thereby achieving the clamping and separation of the clamping sub-assemblies 10 at both ends.

[0130] In actual operation, the rotation direction of the first rotating motor 21 can be switched automatically by an application program, or the rotation direction of the first rotating motor 21 can be switched electrically by a key. Figure 4 As shown, the wire clamping assembly includes a motor driver for controlling the direction and magnitude of the current output to the first rotating motor 21, thereby controlling the direction and speed of the first rotating motor 21.

[0131] In one embodiment, before clamping the drain wire 100 (see Figure 5 ), when the first rotating motor 21 is blocked, it is considered to have reached the clamping position, and the first rotating motor 21 can be controlled to stop at this time.

[0132] In the embodiment of the present disclosure, the first transmission mechanism 22 is a first screw transmission mechanism, comprising:

[0133] A first screw rod 221 extending along a first direction AA' is divided into a forward thread segment and a reverse thread segment along the first direction AA', and a first rotation input end 2c is formed on the first screw rod 221;

[0134] The first sliding members 222 on both sides are connected to the forward thread segment and the reverse thread segment respectively through the first screw transmission pair, each first sliding member 222 is connected to the supporting part 11 of the wire clamping sub-component 10 on the corresponding side, and the first translation output ends 2a at both ends are correspondingly formed on the first sliding members 222 on both sides.

[0135] In this embodiment, the first screw transmission pair is configured such that two first sliding members 222 are sleeved on the first screw 221 and are threadedly connected to the threaded segments on the corresponding sides, and at the same time, the first sliding member 222 is rotationally limited, so that the rotational motion of the first screw 221 can be converted into linear motion of the two first sliding members 222.

[0136] Since the spiral directions of the forward thread segment and the reverse thread segment are opposite, when the first screw rods 221 on both sides rotate, the movement directions of the two first sliding members 222 along the first direction AA' are opposite. In this way, by controlling the rotation directions of the first screw rod 221 to be opposite, the first sliding members 222 on both sides can move toward or away from each other, and further synchronously realize the movement of the clamping sub-component 10 toward or away from each other to achieve a clamped state or a separated state.

[0137] Therefore, by controlling the first rotary motor 21 to rotate forward and reverse, the rotation direction of the first screw rod 221 can be changed, and finally the clamping and separation of the two side clamping sub-components 10 can be achieved. In this embodiment, the accuracy of the electric signal control is relatively high.

[0138] In the embodiments of the present disclosure, Figure 6 As shown, the rotation limit of the first sliding member 222 on each side can be set as follows: the first transmission mechanism 22 also includes a track 223 arranged in parallel with the first screw rod 221, and each first sliding member 222 forms a sliding fit with the track 223, such as a slide rail and slide groove structure. In this way, the rotational movement of each first sliding member 222 is limited by the track 223, and then converted into a linear motion along the track 223.

[0139] In another embodiment, the track may not be provided. For example, the bottom surface of each first sliding member is a plane or other irregular shapes, which cooperates with the surface of the base below to achieve rotation limitation.

[0140] like Figure 4 As shown, in the embodiment of the present disclosure, the first rotation input end 2c of the first screw rod 221 is connected to the first motor output end 2b through the third gear transmission mechanism 24. Specifically, the first motor output end 2b is coaxially connected with a first gear 241, and the second gear 242 is coaxially connected to one end of the first screw rod 221, and the first gear 241 and the second gear 242 form a gear pair. In this way, the first rotation input end 2c is formed on the second gear 242, and the rotational motion output by the first rotary motor 21 is transmitted to the first screw rod 221 through the third gear transmission mechanism 24.

[0141] In another embodiment, the first rotary motor and the first screw rod may be connected via a belt transmission mechanism. For example, the output end of the first rotary motor is coaxially connected to the driving wheel, the first screw rod is coaxially connected to the driven wheel, the driven wheel forms the first rotary input end, and a transmission belt is tensioned between the driving wheel and the driven wheel to transmit the rotary motion of the driving wheel to the driven wheel and the first screw rod.

[0142] In an optional embodiment, the third gear transmission mechanism or belt transmission mechanism may not be provided, but the output end of the first rotating motor may be directly coaxially connected to the first screw rod to achieve synchronous rotation. These embodiments may be selected according to the specific installation environment and are not limited here.

[0143] These implementation methods can be designed according to specific application scenarios and installation environments.

[0144] In an optional embodiment, a first driving mechanism such as a linear motor or a translation cylinder is used to replace the first driving mechanism in the present embodiment, for example, a linear motor directly outputs a linear motion. At this time, a linear motor is set corresponding to the clamping sub-assembly on one side, and the linear motor can be controlled to drive the clamping sub-assembly on the one side to move linearly to achieve clamping and separation. In another embodiment, linear motors can be set corresponding to the clamping sub-assemblies on both sides, and the linear motors on both sides are synchronously controlled to move toward or away from each other synchronously to drive the clamping sub-assemblies on both sides to move toward or away from each other synchronously.

[0145] In this embodiment, the first rotating motor cooperates with a set of first transmission mechanisms to complete the clamping and opening of the clamping sub-components on both sides. This structure uses fewer components and has a high degree of control. In an optional embodiment, a set of first drive mechanisms based on a motor-screw transmission mechanism can also be set corresponding to each side of the clamping sub-component to achieve separate control of each side of the clamping sub-component.

[0146] In the embodiment of the present disclosure, the wire clamping assembly further includes:

[0147] First support structure 25. At this time, both side clamping sub-components 10 and first driving mechanism 20 are installed on the first support structure 25, and the first support structure 25 provides support and installation functions. Exemplarily, as described above, the track 223 is formed on the first support structure 25.

[0148] As mentioned above, the clamping assembly provided in the embodiment of the present disclosure is particularly suitable for dragging the drainage line 100 (see Figure 5 ) In the scenario of delivering the wire, it is possible to prevent the difficulty in dragging and damage to the drainage wire 100 caused by twisting during dragging.

[0149] In the embodiments of the present disclosure, Figure 7 and Figure 8 As shown, in the clamping assembly 1, the side wire clamping position S12 (such as Figure 1 The clamping sub-component 10 on one side includes:

[0150] The hollow second support structure 71 is connected to the first translation output end 2a ( Figure 7 (Obscured and not visible) transmission connection;

[0151] The clamping claw body 72 installed with the second supporting structure 71 is configured to slide with the second supporting structure 71 along the second direction BB'. The clamping claw body 72 has a retracted position w1 and an extended position w2 along the second direction BB' relative to the second supporting structure 71.

[0152] The spring 73 ( Figure 7 The two ends of the spring 73 along the deformation direction are respectively fixed to the inner wall of the second support structure 71 and the clamp body 72, and the deformation direction is parallel to the second direction BB'.

[0153] The spring 73 is configured to elastically deform when the clamping jaw body 72 is pressed to slide from the extended position w2 to the retracted position w1, and to drive the clamping jaw body 72 to return to the extended position w2 when the clamping jaw body 72 is released from the pressure.

[0154] A limited position matching assembly 75 is arranged between two opposite sides of the clamping jaw body 72 and the support seat 74 along the first direction AA', and the limited position matching assembly 75 includes a limited position column 751 and a limited position groove (which is blocked and invisible) extending along the first direction AA', wherein the support seat 74 is fixedly installed with the first support structure 25 (as the term of the same name above), so that the support seat 74 is fixedly arranged relative to the clamping jaw body 72. Among them, the limited position column 751 is installed on the inner side surface of the support seat 74, so that the limited position groove is formed on the outer side surface of the clamping jaw body 72, and the installation positions of the limited position column 751 and the limited position groove are replaceable.

[0155] When working, if Fig. 9 As shown, in the direction of the drainage line 100 (see Figure 5 ) Before the position transfer of the ignition device, the clamp body 72 is first pressed to the retracted position w1, at which time the spring 73 is compressed; then, the first drive mechanism 20 (see Figure 4 ) drives the two side clamping sub-assemblies 10 to move away from each other, so that the clamping claw body 72 and the inner side surface of the support seat 74 are close to each other, so that the limit column 751 (refer to Figure 7 ) is inserted into the limiting groove, thereby limiting the clamping jaw body 72 to the retracted position w1.

[0156] When transferring the ignition device to the drain line 100 (see Figure 5 ) position, the clamp body 72 is in the retracted position w1, which does not form any obstacle to the drainage line 100, and allows the drainage line 100 to be smoothly inserted into the clamping area from this side. Fig.10 As shown, after the drainage line 100 enters the clamping area, the first driving mechanism 20 (see Figure 4 ) drives the clamping sub-assemblies 10 on both sides to move toward each other, so that the limiting column 751 (such as Figure 7 As shown in the figure, the clamping claw body 72 disengages from the limiting groove, and the clamping claw body 72 returns to the extended position w2 driven by the spring 73, and continues to move toward the clamping wire sub-component 10 on the other side, thereby clamping the drainage wire 100 with the clamping wire sub-component 10 on the other side.

[0157] From the above, we can see that Fig. 9 As shown, by means of the above-mentioned limiting matching component 75 (such as Figure 7 As shown in FIG. 1 , the initial state of the clamp body 72 is in the retracted position w1, and the initial state of the corresponding spring 73 is in the stretched state. At this time, the drainage line 100 (see FIG. 1 ) Figure 5 ) can easily and smoothly enter the clamping area from one side of the clamping claw body 72 in the retracted position w1, thereby improving the efficiency and reliability of the line entry operation of the drainage line 100 relative to the ignition device.

[0158] In an optional embodiment, the limiting fitting assembly may not be designed. The clamp body is in an extended position in the initial state, at which time the spring is in a zero deformation state or has a certain deformation, and the clamp body and the second supporting structure remain relatively stable. During operation, the drainage line squeezes the clamp body from one side of the clamp body, causing the spring to be compressed and deformed, and the clamp body can move downward, that is, retract into the second supporting structure. Then the clamp body will not hinder the insertion of the drainage line, and the drainage line reaches the clamping area between the two side clamping sub-components. At this time, the spring is reset, driving the clamp body to pop up. Afterwards, the first driving mechanism is controlled to drive the two side clamping sub-components to move toward each other to clamp the drainage line.

[0159] This embodiment provides a retractable clamping wire assembly design, which can be used to clamp the drainage wire 100 (see Figure 5 ) is inserted into the clamping area from one side of the clamping claw body 72 in the retracted position w1 to improve the reliability of the power operation.

[0160] In this embodiment, if Figure 8 As shown, the spring 73 is located on the side of the clamp body 72, and the two ends of the spring 73 along the deformation direction are respectively fixed to the side 721 of the clamp body 72 and the top surface of the inner wall of the second support structure 71 (not shown in the figure). For example, the spring 73 is fixedly connected to the bottom of the side 721 of the clamp body 72.

[0161] Thus, when the clamp body 72 is in the retracted position w1 (eg Fig. 9 As shown), the spring 73 is in a stretched state and can be in a position where the limit post 751 (as shown) Figure 7 When the clamping jaw body 72 is disengaged from the limiting groove, the tension deformation is released to restore the tension state to the zero deformation state, ensuring that the clamping jaw body 72 returns to the extended position w2 (as shown in FIG. Fig.10 shown).

[0162] In this embodiment, the spring 73 is a tension spring. Compared with the compression spring, the tension spring does not occupy the bottom area of ​​the clamp body sub-component, so there is no need to reserve space for installation and compression in the bottom area, which greatly saves occupied space.

[0163] In this embodiment, if Figure 8 As shown, the side surface of the clamp body 72 is connected to the inner side surface of the second support structure 71 via a sliding fit assembly 76 . The sliding fit assembly 76 includes a second groove rail 761 extending along the second direction BB′ and a slider 762 slidingly matched with the second groove rail 761 .

[0164] The bottom end of the second groove rail 761 defines a retracted position w1, and the top end of the second groove rail 761 defines an extended position w2 (eg, Fig.10 shown).

[0165] The sliding fit assembly 76 can ensure that the clamping jaw body 72 moves smoothly relative to the second support structure 71, thereby improving the reliability of product operation. At the same time, the sliding fit assembly between the second groove rail 761 and the slider 762 can improve the product integration.

[0166] In this embodiment, the second groove rail 761 is installed on the side of the clamp body 72, and the slider 762 is installed on the inner side of the second support structure 71. Alternatively, the second groove rail is installed on the inner side of the second support structure, and the slider is installed on the side of the clamp body.

[0167] In the embodiment of the present disclosure, the spring 73 and the sliding fitting assembly 76 are arranged on the same side of the clamp body 72, which is designed according to the current installation environment and can also be arranged on different sides.

[0168] The spring 73 and the sliding fitting assembly 76 are specifically arranged on the same side of the clamp body 72 along the third direction CC' parallel to the axial direction. This can prevent these components from affecting the first transmission mechanism 22 (such as Figure 4 As shown in the figure, transmission interference is generated, which is beneficial to improve product feasibility.

[0169] In this embodiment, springs 73 and sliding fitting components 76 are provided on both sides of the clamp body 72 along the third direction CC', so that the forces on both sides of the clamp body 72 are more balanced to prevent it from tilting to one side.

[0170] In the embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the wire clamping sub-component 10 on the other side close to the busbar side wire clamping position S12 is fixedly installed on the base 90 and is in a fixed state during the fire connection operation.

[0171] In one application scenario, each wire clamp assembly position S1 includes a drain line side wire clamp position S11 and a busbar side wire clamp position S12 located on both sides of the bolt installation position S2 along the first direction AA'. When the wire clamp 40 to be installed is pre-tightened and installed on the ignition connection device, a drain line wire clamp space 4a and a busbar wire clamp space 4b are formed between the upper and lower wire clamp parts 41 and 42 of the wire clamp 40 to be installed. Along the second direction BB', the drain line wire clamp space 4a corresponds to the position of the drain line side wire clamp position S11, and the busbar wire clamp space 4b corresponds to the position of the busbar side wire clamp position S12.

[0172] When using the fire connection device of this embodiment, the wire clamp 40 to be installed is placed in the wire clamp assembly position S1, and the upper and lower wire clamp parts 41 and 42 of the wire clamp 40 to be installed are pre-tightened by bolts 50. Two bolt installation positions S2 are provided in each wire clamp assembly position S1 along the third direction CC', and each bolt installation position S2 is pre-tightened with a corresponding bolt 50. The bolt 50 is threadedly matched with the upper wire clamp part 41, and its bolt head is screwed with the screw assembly 91 (such as Figure 3 The corresponding sleeve structure shape matches.

[0173] In the initial state of the fire connection device, the clamp body 72 is in the retracted position w1 (eg Fig. 9 shown).

[0174] Operate the robot arm to install the above fire connection device, and transfer the fire connection device to the lower drainage line 100 (such as Figure 5 As shown in the figure, the drainage line 100 in the ready state has a gripping section, the gripping section is straightened in advance and its two ends are clamped on the side wall of the bucket arm truck of the insulating bucket.

[0175] The robot adjusts the posture of the fire connection device so that the third direction CC' is parallel to the drain line 100, and in the second direction BB', the drain line 100 corresponds to the projection of the clamping area between the two side clamping sub-components 10. At this time, the drain line 100 is located outside the clamping claw body 72 connected with the spring 73.

[0176] Afterwards, the robot arm moves along the first direction AA' toward the drainage line 100 (see Figure 5 ) moves the fire connection device, so that the drain wire 100 enters the clamping area between the two side clamping sub-components 10 from one side of the clamping claw body 72 connected to the spring 73, until the drain wire 100 touches the clamping sub-component 10 on the other side close to the busbar side line clamping position S12 and fixedly installed on the base 90 along the second direction BB'. The fire connection device is difficult to continue to move along the first direction AA' due to the obstruction of the drain wire 100. The drain wire 100 squeezes the first elastic member 92 to contract inward, triggering the first optical coupler to generate a drain wire detection signal, and the drain wire detection signal controls the first drive mechanism 20 (such as Figure 4 As shown in FIG. 1 ) drives the clamping sub-assemblies 10 on both sides to move toward each other, thereby causing the limiting column 751 (as shown in FIG. Figure 7 As shown in the figure, the guide wire 100 is disengaged from the limiting groove, and finally the guide wire 100 is inserted and clamped.

[0177] Since the outlet ends D1 of the drain wires at both ends correspond to the clamping area between the clamping sub-components 10 on both sides along the third direction CC', the drain wire 100 also enters the clamping area between the clamping sub-components 10 on both sides and enters the side clamping position S11 of the drain wire. Figure 5 The drain wire 100 is then clamped by the two side clamping sub-components 10 (shown in FIG. 1 ).

[0178] Next, the structural member fixing the drainage line 100 on the side wall of the bucket arm loosens the drainage line 100, and the mechanical arm transfers the fire connection device to the high busbar 200 (such as Figure 5 As shown in the figure, the fire connection device drags the drain wire 100 upward during the movement. After the fire connection device reaches the high busbar 200, the busbar 200 enters the busbar side clamp position S12, and the busbar 200 is placed in the busbar clamp space 4b between the upper and lower clamp parts 41 and 42.

[0179] Afterwards, control the screwing assembly 91 (such as Figure 3 As shown in FIG. 1 , the bolt 50 is screwed on and the upper clamp 41 is moved downward by limiting the axial position of the bolt 50 until the upper and lower clamps 41 and 42 are gradually closed to the clamping position to clamp the busbar 200 (see FIG. 1 ). Figure 5 ) and drainage line 100 (see Figure 5 ), the installation of the wire clamp 40 to be installed is completed.

[0180] After the wire clamp 40 is installed in place, the control screw assembly 91 (such as Figure 3 At this time, the control arm transfers the fire connection device so that the fire connection device is separated from the wire clamp 40 to be installed.

[0181] The fire connection device of this embodiment can automatically complete the live fire connection operation, which not only improves the operation efficiency, but also improves the operation safety.

[0182] The fire connection device of this embodiment can be used in conjunction with a boom truck. For example, the fire connection device with a pre-tightening wire clamp is pre-installed on the boom truck, and the mechanical arm on the boom truck is controlled to grab the fire connection device and move it to the drainage line 100 (such as Figure 5 ) and busbar 200 (as shown Figure 5 ) position so that the drainage line 100 (as shown Figure 5 ) and busbar 200 (as shown Figure 5 As shown in FIG. 1 ) respectively into the drain wire clamp space 4a and the busbar clamp space 4b, and further tighten the clamp 40 to be installed to fix the busbar 200 (as shown in FIG. Figure 2 ) and drainage line 100 (as shown Figure 5 as shown) overlapped together.

[0183] In the embodiments of the present disclosure, Figure 1 As shown, a pair of wire clamp assembly positions S1 are provided on the base 90, and two wire clamps 40 to be installed can be installed at the same time, so that the busbar 200 (such as Figure 5 ) and drainage line 100 (as shown Figure 5 As shown in the figure, the wires can be overlapped by a pair of wire clamps 40 to make the overlapping connection more secure.

[0184] In this embodiment, the clamping assembly of this embodiment is used, such as Fig. 9 As shown, in each side of the clamping sub-component 10, a clamping area is formed between two adjacent rollers 12, and the clamping areas of the clamping sub-components 10 on both sides together form a clamping space. During operation, the clamping sub-components 10 of the clamping assembly 1 are in a separated state. Fig.10 As shown, the operating robot arm carries the ignition device and moves to the drainage line 100 (see Figure 5 ) position, and from the side of the clamp body 72 connected to the spring 73, the drainage line 100 (such as Figure 5 As shown in the figure, the clamping claw 72 is inserted into the pre-tightened clamping space and between the clamping sub-components 10 on both sides. Driven by the spring 73, the clamping claw body 72 returns to the extended position w2 and continues to move toward the clamping sub-component 10 on the other side, thereby clamping the drainage wire 100 with the clamping sub-component 10 on the other side. After that, the robot arm is operated to move the fire connection device to the busbar 200 (as shown in the figure). Figure 5As shown in the figure, during the movement, the wire clamping sub-components 10 on both sides clamp the drainage wire 100 to prevent the drainage wire 100 from falling off from the pre-tightened wire clamp, thereby enhancing the operation reliability.

[0185] Drag the drainage line 100 (see Figure 5 ), the drainage line 100 twists and is subject to the frictional resistance of the roller 12. Since the roller 12 is rotatable, the torsional force applied by the drainage line 100 to the roller 12 can overcome the frictional resistance of the roller 12 and drive the roller 12 in contact with it to roll. In this way, the drainage line 100 can continue to twist, preventing the drainage line 100 from being tightened more seriously and making it more difficult to drag.

[0186] In the embodiments of the present disclosure, Figure 1 As shown, the fire connection device also includes:

[0187] The first elastic member 92 and the first optical coupler (blocked and invisible), the first elastic member 92 corresponds to the position of the drainage line side wire clamp S11 along the third direction CC', and is closer to the drainage line entry end D2 than the first optical coupler along the first direction AA'. The drainage line entry end D2 is the end of the drainage line side wire clamp S11 along the first direction AA' away from the bolt installation position S2.

[0188] The first elastic member 92 is located in the area between the drainage line side line clamping positions S11 of the two sets of line clamping assembly positions. The drainage line 100 (see Figure 5 ) along the first direction AA' from the drain wire entry end D2 into the drain wire clamp space 4a (such as Figure 2 ), and at the same time, the first elastic member 92 is squeezed to contract inward, triggering the first optical coupler to generate a drainage line detection signal, and the drainage line detection signal controls the first driving mechanism 20 (as shown Figure 5 As shown in FIG. 1 ) drives the clamping sub-assemblies 10 on both sides to move toward each other, thereby causing the limiting column 751 (as shown in FIG. Figure 7 As shown in the figure) disengages from the limiting groove, and finally the drainage line 100 is clamped.

[0189] In the embodiment of the present disclosure, two sets of clamping components 1 are arranged on the base 90, which are respectively located outside the two sets of clamping assembly positions S1 along the third direction CC'. The two sets of clamping components 1 are arranged on the drainage line 100 (see Figure 5 ) During the transfer process, the dragging force on the drainage line 100 can be increased to prevent the drainage line 100 from shaking and detaching.

[0190] In an optional embodiment, the first elastic member 92 and the first optical coupler matched therewith are arranged between the two sets of wire clamp assembly positions S1 and close to the drainage line entry end D2 of the wire clamp assembly position S1, so as to ensure that the drainage line 100 (see Figure 5) can only squeeze the first elastic member 92 after entering the clamping area of ​​the two sets of clamping components 1 and the two sets of clamping assembly positions S1, thereby triggering the first optical coupler to ensure that after the first driving mechanism 20 is started, the two sets of clamping components 1 accurately clamp the drainage line 100.

[0191] In another embodiment, the positions of the first elastic member and the first optical coupler may be set according to a specific operating environment.

[0192] In the embodiments of the present disclosure, reference Figure 1 and Figure 2 The fire connection device further comprises: two groups of line catching claw assemblies 93 arranged along the third direction CC';

[0193] Combination Fig.11 The wire catching claw assembly 93 includes a wire catching claw 931 and a second driving mechanism 932 which is transmission-connected to the wire catching claw 931;

[0194] refer to Figure 1 and Fig.11 The wire catching claw 931 has a free end 8a, a connecting portion 8b and an inner concave surface 810 extending from the connecting portion 8b to the free end 8a. The inner concave surface 810 is directed toward the wire clamp assembly position S1 ( Fig.11 On one side of the housing (not shown), the inner concave surface 810 is configured to form a fishing line space S;

[0195] The connecting portion 8b is higher than the base 90 and is fixed to the third supporting structure 94 (such as Fig.12 As shown) is rotatably installed by a second rotating shaft 83, the second rotating shaft 83 extends along a third direction CC', and the third supporting structure 94 provides support and installation for the line fishing claw 931;

[0196] The second driving mechanism 932 is configured to control and drive the line catching claw 931 to rotate around the second rotating shaft 83 at the first position L1 ( Figure 1 The left line catching claw 931 position shown) and the second position L2 ( Figure 1 The right side line catching claw 931 is rotated between the first position L1 and the second position L2, and the free end 8a is closer to the base 90 than the second position L2.

[0197] Combination Figure 5 The busbar 200 is overlapped on the high electric pole and is in a suspended shape with a certain curvature due to the influence of gravity. It is difficult for the busbar 200 to enter the busbar clamp space 4b of the two sets of clamps 40 to be installed by operating the mechanical arm to move the fire connection device. This embodiment provides a wire catching claw assembly 93, which can facilitate the busbar wire catching and pull the busbar 200 into the busbar clamp space 4b of the clamp 40 to be installed, thereby improving the reliability of the fire connection operation.

[0198] During operation, the robot arm is operated to move the fire connection device. When the busbar 200 enters the wire catching range of the wire catching claw 931, the second driving mechanism 932 is controlled to drive the wire catching claw 931 to rotate toward the wire clamp assembly position S1, and the busbar 200 enters the wire catching space S. The wire catching claw 931 is continuously rotated to make the wire catching claw 931 rotate downward to hold the wire and press the busbar 200 downward. Then, the busbar 200 is pulled toward the wire clamp 40 to be installed along the first direction AA' in combination with the wire catching claw 931, so that the busbar 200 is squeezed into the busbar wire clamp space 4b (such as Figure 2 shown).

[0199] In another embodiment, if the wire catching claw assembly is not provided, the firing device can be driven to move by controlling the mechanical arm so as to push the busbar 200 into the busbar side wire clamping position.

[0200] In this embodiment, if Figure 2 As shown, the fire connection device is provided with two sets of wire catching claw assemblies 93 arranged along the third direction CC', respectively located at the two ends of the base 90. By providing two sets of wire catching claw assemblies 93, the busbar 200 (see Figure 5 ) enters the two sets of wire clamp assembly positions S1, and can provide greater gripping force to grasp the busbar 200, providing reliability for busbar catching and insertion.

[0201] In the disclosed embodiment, the wire catching claw 931 and the busbar side wire clamping position S12 are staggered along the first direction AA', so that the wire catching range of the wire catching claw 931 is located on one side of the busbar side wire clamping position S12 along the third direction CC' and overlaps.

[0202] When fishing, combine Figure 1 As shown, the wire catching claw 931 rotates toward the direction close to the base 90, and the free end 8a reaches the first position L1, that is, close to the base 90, and the wire catching space S overlaps with the busbar side wire clamping position S12 along the third direction CC'. Figure 5 ) is pressed down, and the inner concave surface 810 is pushed inward while pressing the busbar 200, so that the busbar 200 is located outside the busbar entry end D3 of the busbar side clamp position S12, so that it is pushed into the busbar clamp space 4b (such as the busbar clamp space 4b) where the clamp 40 is to be installed from the busbar entry end D3. Figure 2 Wherein, the busbar entry end D3 is an end of the busbar side line clamping position S12 away from the bolt installation position S2 along the first direction AA'.

[0203] Therefore, this staggered design can prevent the wire catching claw 931 from interfering with the wire clamp 40 to be installed on the wire clamp assembly position S1 when rotating, and also expand the wire catching range of the wire catching claw 931, thereby improving the reliability of wire catching. In particular, this design ensures that the distance between the wire catching claw 931 and the wire clamp assembly position S1 along the first direction AA' does not need to be too large, thereby ensuring the layout and installation rationality of the wire catching claw assembly 93 as a whole.

[0204] In the embodiments of the present disclosure, Fig.11 As shown, the line catching claw 931 also has a driving end 8c, and the connecting portion 8b is arranged between the free end 8a and the driving end 8c; the second driving mechanism 932 includes:

[0205] A second rotary motor 9320 having a second motor output terminal 82a;

[0206] The second transmission mechanism 820 having a second rotation input end 82b and a second translation output end 82c is transmission-connected to the second motor output end 82a via the second rotation input end 82b to input rotational motion, and the second translation output end 82c is connected to the driving end 8c via a connecting rod 84.

[0207] Combination Fig.11 and Fig.12 The second transmission mechanism 820 is configured to convert the rotational motion of the second rotation input end 82b into the translational motion of the second translation output end 82c along the second direction BB', and the translational motion pushes the driving end 8c through the connecting rod 84 to make the line catching claw 931 rotate around the second rotating shaft 83.

[0208] In this embodiment, the second translation output end 82c translates along the second direction BB'. The connecting rod 84 translates along with the second translation output end 82c and rotates around the second translation output end 82c, further driving the driving end 8c of the line catching claw 931 to move together. Since the second rotating shaft 83 is fixed in position, the driving end 8c rotates around the second rotating shaft 83, realizing synchronous rotation of the free end 8a.

[0209] When the second translation output end 82c moves upward, the connecting rod 84 moves upward and pushes the driving end 8c to rotate upward, and the free end 8a rotates downward. Conversely, when the second translation output end 82c moves downward, the free end 8a rotates upward.

[0210] Therefore, by controlling the second rotating motor 9320 to rotate forward and reverse, the wire catching claw 931 can be driven to rotate reciprocatingly, thereby achieving precise control of the fire connection operation.

[0211] In the embodiments of the present disclosure, Fig.11 As shown, the second transmission mechanism 820 is configured to convert the rotational motion into the translational motion, which may adopt a screw transmission mechanism, including:

[0212] A second screw rod 821 extending along a second direction BB′, and a second rotation input end 82b is formed on the second screw rod 821;

[0213] The second sliding member 822 is installed through the screw transmission pair and the second screw 821, and the second translation output end 82c is formed on the second sliding member 822.

[0214] In this embodiment, the screw transmission pair is configured such that the second sliding member 822 is sleeved on the second screw rod 821 and forms a threaded fit with the second screw rod 821 , and the second sliding member 822 is rotationally limited, so that the rotational motion of the second screw rod 821 can be converted into the linear motion of the second sliding member 822 .

[0215] Therefore, by controlling the second rotary motor 9320 to rotate forward and reverse, the rotation direction of the second screw rod 821 can be changed, and finally the line catching claw 931 can be reciprocated. In this embodiment, the accuracy of the electric signal control is high.

[0216] In the embodiments of the present disclosure, Fig.12 As shown, the rotation limit of the second sliding member 822 can be set as follows: the third support structure 94 forms a limited space 12a, and the inner wall of the limited space 12a forms a rotation limit for the second sliding member 822, so that the second sliding member 822 can slide along the inner wall of the limited space 12a.

[0217] In the embodiments of the present disclosure, Fig.11 As shown, the second rotation input end 82b of the second screw rod 821 is connected to the second motor output end 82a via a first gear transmission mechanism 85. Specifically, a driving gear 851 is coaxially connected to the second motor output end 82a, and a driven gear 852 is coaxially connected to the second rotation input end 82b, and the driving gear 851 and the driven gear 852 form a gear pair.

[0218] In another embodiment, the second rotary motor and the second screw rod may be connected via a belt transmission mechanism. For example, the output end of the second motor is coaxially connected to the driving wheel, the second screw rod is coaxially connected to the driven wheel, the driven wheel forms the second rotary input end, and a transmission belt is tensioned between the driving wheel and the driven wheel to transmit the rotary motion of the driving wheel to the driven wheel and the second screw rod.

[0219] In an optional embodiment, the gear transmission mechanism or the belt transmission mechanism may not be provided, but the second motor output end is directly coaxially connected with the second screw rod to achieve synchronous rotation. These embodiments can be selected according to the specific installation environment and are not limited here.

[0220] In an optional embodiment, the second transmission mechanism may not be provided, and a second rotating motor may be connected to the rotating shaft to directly drive the line catching claw to rotate around the rotating shaft.

[0221] These implementation methods can be designed according to specific application scenarios and installation environments.

[0222] In an optional embodiment, a linear motor or a translation cylinder or other driving mechanism is used to replace the second driving mechanism in this embodiment. For example, the translation output end of the linear motor directly outputs linear motion, and the translation output end of the linear motor is connected to the driving end of the line catching claw through a connecting rod, and the translation output of the translation output end of the linear motor is converted into the rotation of the line catching claw.

[0223] In the embodiments of the present disclosure, Fig.11 and Fig.12 As shown, the fire connection device also includes:

[0224] Having a third translation output terminal 95a ( Fig.12 The third driving mechanism 95 (which is blocked and invisible) is connected to the wire catching claw assembly 93 through the third translation output end 95a, and is configured to be controlled to drive the wire catching claw assembly 93 to translate along the first direction AA'.

[0225] During operation, the second driving mechanism 932 is first controlled to drive the wire catching claw 931 to scoop up the wire and press it down, and then the third driving mechanism 95 is controlled to drive the wire catching claw 931 to move toward the wire clamp 40 to be installed (such as Figure 2 As shown in FIG. 1 , the busbar 200 is moved to the busbar clamp space 4b (as shown in FIG. Figure 2 During the operation, the second driving mechanism 932 and the third driving mechanism 95 can be coordinated and controlled according to the actual situation to achieve operations such as busbar holding and insertion.

[0226] Combination Figure 2 and Fig.13 As shown, a receiving groove 10a is formed in the base 90, and the receiving groove 10a has a first limiting end 10b and a second limiting end 10c extending along the first direction AA', the first limiting end 10b corresponds to the busbar side line clamping position S12 along the third direction CC', and the second limiting end 10c is away from the busbar side line clamping position S12 and the drainage line side line clamping position S11 along the first direction AA'; the wire catching claw assembly 93 forms a sliding fit with the bottom wall of the receiving groove 10a, and the third driving mechanism 95 drives the wire catching claw assembly 93 to move horizontally along the first direction AA' between the two ends of the receiving groove 10a.

[0227] In this embodiment, the receiving groove 10a is L-shaped, and has a narrow and long area extending along the first direction AA', and its projection along the third direction CC' covers the busbar side wire clamp position S12 of the wire clamp assembly position S1. Figure 5) and press down, control the third driving mechanism 95 to drive the wire catching claw 931 to move forward to the busbar wire entry end D3 position of the wire clamp 40 to be installed or further forward, so that the busbar 200 can enter the busbar wire clamp space 4b of the wire clamp 40 to be installed.

[0228] As mentioned above, the wire catching claw 931 and the adjacent wire clamp assembly position S1 are staggered along the first direction AA', which to some extent expands the wire catching range of the wire catching claw 931 when rotating forward. Figure 5 ) and presses it down to prevent the busbar 200 from escaping, and then the third driving mechanism 95 further controls the wire-catching claw 931 to move forward to pull the busbar 200 into the wire clamp 40 to be installed.

[0229] In actual use, the second drive mechanism 932 and the third drive mechanism 95 are coordinated and controlled to complete the busbar line catching and line insertion operations, thereby improving the reliability of the automated control of the fire connection operation.

[0230] In the embodiments of the present disclosure, Fig.12 and 13 As shown, the third driving mechanism 95 may include:

[0231] A third rotating motor 950 having a third motor output terminal 95b;

[0232] It has a third rotation input end 95c and a third translation output end 95a (see Fig.11 ) is connected to the third motor output terminal 95b through the third rotation input terminal 95c to input rotational motion, and the third transmission mechanism 901 is configured to convert the rotational motion of the third rotation input terminal 95c into translational motion of the third translational output terminal 95a along the first direction AA'.

[0233] In this embodiment, the third rotary motor 950 is controlled to switch the rotation direction, the rotation direction of the third rotary input end 95c is changed, and the third translation output end 95a is switched to move in the first direction AA', thereby achieving synchronous translation of the line catching claw 931.

[0234] In this embodiment, the line catching claw 931 is fixedly installed in the third supporting structure 94 to form a line catching claw assembly 93. In this way, the line catching claw assembly 93 is finally installed with the third translation output end 95a through the third supporting structure 94 to move synchronously with the third translation output end 95a.

[0235] In the embodiments of the present disclosure, Fig.12 As shown, the third transmission mechanism 901 is configured to convert rotational motion into translational motion, which may adopt a screw transmission mechanism, including:

[0236] A third screw rod 9011 extending along the first direction AA′, and a third rotation input end 95c is formed on the third screw rod 9011;

[0237] The third sliding member 9012 is installed through the third screw transmission pair and the third screw 9011, and the third translation output end 95a is formed on the third sliding member 9012.

[0238] In this embodiment, the third screw transmission pair is configured such that the third sliding member 9012 is sleeved on the third screw rod 9011 and forms a threaded fit with the third screw rod 9011, and the third sliding member 9012 is rotationally limited, so that the rotational motion of the third screw rod 9011 can be converted into the linear motion of the third sliding member 9012.

[0239] Therefore, by controlling the third rotary motor 950 to rotate forward and reverse, the rotation direction of the third screw rod 9011 can be changed, and finally the reciprocating translation of the line catching claw 931 can be achieved. In this embodiment, the accuracy of the electric signal control is relatively high.

[0240] In this embodiment, the third supporting structure 94 is installed on the third sliding member 9012 and moves in translation along with the third sliding member 9012 .

[0241] In the embodiment of the present disclosure, the rotation limit of the third sliding member 9012 can be set as follows: the third sliding member 9012 and the receiving groove 10a (such as Fig.13 The bottom wall of the accommodating groove 10a forms a sliding fit, and the inner wall of the accommodating groove 10a can form a rotation limit for the third sliding member 9012, thereby converting it into movement of the third sliding member 9012 along the first direction AA'.

[0242] In the embodiments of the present disclosure, Fig.12 As shown, the third rotation input end 95c of the third screw rod 9011 is connected to the third motor output end 95b via a second gear transmission mechanism 96. Specifically, a third motor gear 961 is coaxially connected to the third motor output end 95b, an input end gear 962 is coaxially connected to the third rotation input end 95c, a transmission gear 963 is arranged between the third motor gear 961 and the input end gear 962, and the transmission gear 963 transmits rotational motion between the third motor gear 961 and the input end gear 962.

[0243] In another embodiment, the third rotary motor and the third screw rod may be connected via a belt transmission mechanism. For example, the output end of the third motor is coaxially connected to the driving wheel, the third screw rod is coaxially connected to the driven wheel, the driven wheel forms the third rotary input end, and a transmission belt is tensioned between the driving wheel and the driven wheel to transmit the rotary motion of the driving wheel to the driven wheel and the third screw rod.

[0244] In an optional embodiment, the gear transmission mechanism or the belt transmission mechanism may not be provided, but the output end of the third motor is directly coaxially connected with the third screw rod to achieve synchronous rotation. These embodiments can be selected according to the specific installation environment and are not limited here.

[0245] These implementation methods can be designed according to specific application scenarios and installation environments.

[0246] In an optional embodiment, a linear motor or a translation cylinder or other driving mechanism is used to replace the third driving mechanism in this embodiment. For example, the linear motor directly outputs linear motion, and the translation output end of the linear motor serves as the third translation output end to control the linear motor to directly drive the line catching claw to translate along the second direction.

[0247] In the embodiments of the present disclosure, Figure 1 As shown, the fire connection device also includes:

[0248] The infrared sensor group 98 includes a first radiation unit 101 and a second radiation unit 102 arranged along the second direction BB', wherein the first radiation unit 101 includes a first emitting element 1011 and a first receiving element 1012 arranged opposite to each other along the first direction AA', and the second radiation unit 102 includes a second emitting element 1021 and a second receiving element 1022 arranged opposite to each other along the first direction AA';

[0249] The columns 97 and the support column 900 are arranged on the base 90 at intervals along the first direction AA′, the first emitting element 1011 and the second emitting element 1021 are arranged on the columns 97, and the first receiving element 1012 and the second receiving element 1022 are arranged on the support column 900;

[0250] The upright column 97 corresponds to the second limit end 10c along the third direction CC', and the support column 900 corresponds to the busbar side line clamping position S12 along the third direction CC'.

[0251] During operation, move the fire connection device to busbar 200 (see Figure 5 ) position, the upper first beam unit 101 first senses the busbar 200, indicating that the busbar 200 enters the line catching range of the line catching claw assembly 93, triggering the second driving mechanism 932 (such as Fig.11 The wire claw 931 is driven to rotate downward to press the busbar 200 to prevent the busbar 200 from escaping. When the second beam-receiving unit 102 below senses the busbar 200, it indicates that the busbar 200 is pressed down to the right position, triggering the third driving mechanism 95 (as shown in FIG. Fig.12 As shown in FIG. 1 ), the wire claw 931 is driven to move forward to push the busbar 200 into the wire clamp 40 to be installed (as shown in FIG. 1 ). Figure 2 Busbar clamp space 4b (as shown) Figure 2 shown).

[0252] In the embodiments of the present disclosure, Figure 2 As shown, the fire connection device also includes:

[0253] The second elastic member 99 and the second optical coupler (blocked and invisible), the second elastic member 99 corresponds to the position of the bus side line clamp S12 along the third direction CC', and is closer to the bus entry terminal D3 than the second optical coupler along the first direction AA'. The bus entry terminal D3 is the end of the bus side line clamp S12 along the first direction AA' away from the bolt installation position S2.

[0254] like Figure 2 As shown, when bus 200 (see Figure 5 ) Enters the busbar clamp space 4b from the busbar entry terminal D3, the second elastic member 99 retracts inward, triggering the second optical coupler to generate a busbar detection signal, and confirming that the busbar 200 enters the busbar clamp space 4b. Therefore, the second elastic member 99 cooperates with the second optical coupler to detect whether the busbar 200 enters the busbar clamp space 4b where the clamp 40 is to be installed.

[0255] In this embodiment, the fire connection device includes two sets of wire clamp assembly positions S1, the second elastic member 99 and the second optical coupler are arranged between the two sets of wire clamp assembly positions S1, and are located in the area between the busbar side wire clamp positions S12 of the two sets of wire clamp assembly positions S1, ensuring that the busbar 200 (see Figure 5 ) can only squeeze the second elastic member 99 after correctly entering the busbar wire clamp space 4b corresponding to the two sets of wire clamp assembly positions S1, thereby ensuring the installation quality of the two sets of wire clamps 40 to be installed.

[0256] In another embodiment, other sensing devices such as infrared sensors may be used to replace the second optical coupler detection bus 200 (see Figure 5 ) whether to enter the clamping space.

[0257] In this embodiment, the infrared sensor group 98, the second elastic member 99 and the second optical coupler are provided to control the start and stop of the action of the line catching claw assembly 93, thereby ensuring that the busbar 200 (see Figure 5 ) enters the busbar clamp space 4b where the clamp 40 is to be installed, thereby improving operating efficiency and control accuracy.

[0258] Furthermore, if Figure 1 and Figure 2As shown, the infrared sensor group 98 is installed on the column 97 and the support column 900, and the support column 900 and the column 97 are arranged opposite to each other along the third direction CC' on the base 90. The area between the column 97 and the support column 900 defines the infrared sensing range of the infrared sensor group 98 along the first direction AA'. Specifically, the infrared sensing range corresponds to the translation range of the line catching claw assembly 93 along the first direction AA' and ends at the busbar side line clamping position S12. In this way, when the line catching claw 931 grabs the busbar 200 (see Figure 5 ) and moves along the first direction AA' toward the busbar side clamp position S12, the second emitting unit 102 located below can be kept triggered until the busbar 200 is pulled into the busbar clamp space 4b, and the second elastic member 99 is triggered at the same time, confirming that the busbar 200 is incorporated into the busbar clamp space 4b.

[0259] In this process, if the bus 200 (see Figure 5 ) is detached from the wire catching claw 931, the second shooting unit 102 located below will detect this situation, so that it will change from the triggered state to the non-triggered state, generate a busbar detachment signal, and automatically inform the busbar 200 of the detachment. The next step is to re-control the wire catching claw assembly 93 to grab the busbar 200 until the busbar 200 is pulled into the busbar clamp space 4b.

[0260] Therefore, the infrared sensor group 98 and the second elastic member 99 cooperate with each other to accurately realize the busbar 200 (see Figure 5 ) The detection of the line entry process can further improve the degree of automation control of busbar line entry.

[0261] In addition, the support column corresponds to the busbar side line clamp S12 along the third direction CC', so that the infrared sensing range of the infrared sensor group 98 along the first direction AA' ends at the busbar side line clamp S12, preventing the drainage line 100 clamped by the clamping assembly 1 from accidentally entering the infrared sensing range and causing false triggering.

[0262] The disclosed embodiment also provides a control method based on the above ignition device, such as Fig.14 As shown, the control method includes but is not limited to the following steps:

[0263] Step 1410: when the wire clamp to be installed is pre-tightened by bolts and installed into the wire clamp assembly position, control the ignition device carrying the wire clamp to be installed to move to the drain line position, and control the first driving mechanism to drive the wire clamp assembly to be in an open state, so that the drain line enters the drain line clamp space of the wire clamp to be installed and the clamping area of ​​the wire clamp assembly from the drain line side clamp position along the first direction;

[0264] Step 1420: Control the clamping assembly to clamp the drain wire, and transfer the fire connection device carrying the drain wire to the busbar position, so that the busbar enters the busbar clamp space to be installed with the clamp from the busbar side clamp position along the first direction, and the busbar side clamp position and the drain wire side clamp position are respectively located on both sides of the bolt installation position along the first direction;

[0265] Step 1430: Control the screwing assembly to screw the bolt until the wire clamp to be installed is tightened.

[0266] In one application scenario, combined with Figure 2 As shown, each wire clamp assembly position S1 includes a drain wire side wire clamp position S11 and a bus wire side wire clamp position S12 located on both sides of the bolt installation position S2 along the first direction AA'. When the wire clamp 40 to be installed is pre-tightened and installed on the fire connection device, a drain wire clamp space 4a and a bus wire clamp space 4b are formed between the upper and lower wire clamp parts 41 and 42 of the wire clamp 40 to be installed.

[0267] In this way, during the fire connection operation, the robot arm is first operated to transfer the fire connection device carrying the wire clamp 40 to be installed to the drainage line 100 (see Figure 5 ) position, so that the drainage line 100 enters the drainage line clamp space 4a, and then transfers the fire connection device to the busbar 200 (see Figure 5 ) position, so that the busbar 200 enters the busbar clamp space 4b.

[0268] The fire connection device of this embodiment can automatically complete the live fire connection operation, which not only improves the operation efficiency, but also improves the operation safety.

[0269] In this embodiment, the ignition device transfers the drain line 100 (see Figure 5 ) process, combined with Figure 7 As shown, the clamp assembly 1 clamps the drain wire 100 to prevent the drain wire 100 from falling off from the pre-tightened clamp, thereby enhancing the reliability of the operation. Figure 5 As shown, during the process of dragging and lifting the drainage line 100, since the roller 12 is designed to be rotatable, the torsional force exerted by the drainage line 100 on the roller 12 can overcome the friction resistance of the roller 12, and drive the roller 12 in contact with it to roll. In this way, the drainage line 100 can be continuously twisted, and its wire skin is released due to the rolling friction of the roller 12, which effectively solves the problem of increased dragging difficulty caused by continuous tightening of the wire skin and helps to reduce the risk of friction damage. At the same time, the wire skin will not undergo corresponding twisting relative to the inner core, which can avoid misalignment or displacement of the inner core, thereby ensuring the transmission performance and safety characteristics of the drainage line 100.

[0270] In the embodiments of the present disclosure, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, when the drainage line 100 (see Figure 5 ) before entering the drainage line clamp space 4a of the to-be-installed clamp 40 from the drainage line side clamp position S11 along the first direction AA', the clamp body 72 is placed in the retracted position w1, and the limiting column 751 is inserted into the limiting groove along the first direction AA';

[0271] When the clamp body 72 is in the retracted position w1, the drainage line 100 enters the clamping area between the two side clamping sub-components 10 from one side of the clamp body 72 until the drainage line 100 touches the other clamping sub-component 10, and the drainage line 100 squeezes the first elastic member 92 to shrink inward, triggering the first optical coupler to generate a drainage line detection signal;

[0272] After the drainage line detection signal is generated, the first driving mechanism 20 is controlled to drive the two side clamping components 10 to move toward each other, so that the limiting column 751 is disengaged from the limiting groove, and the clamping claw body 72 returns to the extended position w2 under the elastic force of the spring 73 and clamps the drainage line 100.

[0273] In this embodiment, combined with Fig. 9 As shown, by means of the above-mentioned limiting matching assembly 75, the initial state of the clamp body 72 is in the retracted position w1, and the initial state of the corresponding spring 73 is in the stretched state. Figure 5 ) can easily enter the clamping area from one side of the clamping jaw body 72, thereby improving the efficiency and reliability of the power drainage line operation. This embodiment provides a retractable clamping assembly design, which can push the drainage line 100 from one side of the clamping jaw body 72 into the clamping area, thereby improving the reliability of power operations.

At this time, when executing the above step 1410, the first driving mechanism 20 is controlled to drive the two side clamping sub-members 10 to move toward each other, including:

[0275] When receiving the drainage line detection signal generated by the first optical coupler, the first driving mechanism 20 is controlled to drive the clamping sub-components 10 on both sides to move toward each other in response to the drainage line detection signal. The drainage line detection signal is generated by the drainage line 100 (see Figure 5 ) enters the drainage line clamp space 4a and squeezes the first elastic member 92 to contract, triggering the generation of the first optical coupler.

[0279] When receiving the busbar sensing signal of the second beam-receiving unit 102 located below along the second direction BB′, the third driving mechanism 95 (eg Fig.12 As shown in FIG. 1 ), the wire claw 931 is driven to move along the first direction AA′ toward the wire clamp 40 to be installed, so that the busbar 200 (see FIG. Figure 5 ) Enter the busbar clamp space 4b.

[0281] By using this embodiment, by setting the wire catching claw assembly 93, it is possible to facilitate the busbar wire catching and wire insertion operations, thereby improving the reliability of the fire connection operation. At the same time, in conjunction with the use of the infrared sensor group 98, it is possible to automatically detect the busbar 200 (see Figure 5 ) position, so as to realize automatic control of the rotation and forward translation of the wire claw 931, and ensure that the busbar 200 accurately enters the busbar clamp space 4b. This significantly enhances the automation of the fire connection device operation and improves the efficiency and safety of the fire connection operation.

[0282] Combination Figure 2 and Fig.13 As shown, the fire connection device also includes a second elastic member 99 and a second optical coupler. At this time, when executing the above step 1420, the busbar 200 (see Figure 5 ) along the first direction AA' from the busbar side clamp position S12 into the busbar clamp space 4b where the clamp 40 is to be installed, further comprising:

The bus detection signal is generated by the bus 200 (see Figure 5 ) enters the busbar clamp space 4b and squeezes the second elastic member 99 to contract and trigger the second optical coupler to generate;

[0284] After receiving the busbar detection signal generated by the second optical coupler, the screwing assembly 91 is controlled to screw the bolt 50 until the wire clamp 40 to be installed is tightened;

[0285] After tightening the wire clamp 40, the first driving mechanism 20 drives the wire clamp assembly 1 to be in an open state, the second driving mechanism 932 drives the wire catching claw 931 to open, and the third driving mechanism 95 drives the wire catching claw 931 to move away from the wire clamp 40 along the first direction AA'.

[0286] The second elastic member 99 and the second optical coupler can automatically detect the busbar 200 (see Figure 5 ) enters the drainage line clamp space 4a to achieve precise control and enhance the degree of automated control of this embodiment.

[0289] During the process of screwing the bolt 50, the wire claw 931 keeps pressing down the busbar 200 to prevent the busbar 200 from escaping from the busbar clamp space 4b, until the clamp 40 to be installed is tightened to release the restriction effect on the busbar 200, and the wire claw 931 then returns to its initial position.

[0290] The wire catching claw 931 returns to the initial position, and after the wire clamping assembly 1 releases the drainage wire 100, the robotic arm moves the fire connection device to separate it from the wire clamp, and the fire connection operation is completed.
